-------------------------------------

             Summary: Add ParameterUtil.fromGenericOptionsParser() for compatibility to Hadoop's argument parser
                 Key: FLINK-2018
                 URL: https://issues.apache.org/jira/browse/FLINK-2018
             Project: Flink
          Issue Type: Improvement
            Reporter: Robert Metzger
            Priority: Minor


In FLINK-1525 we've added the {{ParameterTool}}.

For users used to Hadoop's {{GenericOptionsParser}} it would be great to provide a compatible parser.

See: https://hadoop.apache.org/docs/r1.0.4/api/org/apache/hadoop/util/GenericOptionsParser.html


{code}
@Test
public void testFromGenericOptionsParser() {
        ParameterUtil parameter = ParameterUtil.fromGenericOptionsParser(new String[]{"-D", "input=myinput", "-DexpectedCount=15"});
        validate(parameter);
}
{code}
